I´m using NextGEN Gallery 0.98 with WP2.6 and the theme is Mandigo 1.36

Images which I have included with NGG are not centered anymore. they keep staying on the left side, and even wrapping a div with align center round it wont solv the problem. and its not depending on how i write the article. in both the wysiwyg and the html, the images wont be centered.
